Calcifications of the basal ganglia are rarely found at routine autopsies and in skull raiographs. CT is superior to the plain skull raiograhis in detecting intracranial attenuation differences and may be stated to be the method of choice in the diagnosis of intracranial calcifications. Of 5985 brain CT scans performed in Kyung Hee University Hospital during past 3 years, 36 cases were found to have high attenuation lesions suggesting calcifications within basal ganglia. 1. The incidence of basal ganglia calcification on CT scan was about 0.6%. 2. Of these 36 cases , 34 cases were bilateral and the remainder was unilateral. 3. The plain skull films of 23 cases showed visible calcification of basal ganglia in 3 cases(13%). 4. No specific metabilic disease was noted in the cases.
